Acro Disc PSF Syringe Filters w/ Nylon Membrane - 0.45um, 25mm, 1000/Pk
Pall SKU: AP-4502

Pall Acrodisc Nylon Syringe Filters, 0.45 µm, 25 mm, 1000/Pk - AP-4502

Pall Corporation combines proprietary membrane technology with a housing platform validated for both manual and automated filtration workflows. Syringe filters give the analyst a single-use device for clarifying samples right at the bench. The nylon matrix resists particle shedding through extended filtration cycles while clarifying particulates at the rated pore size and ships in economical bulk non-sterile packaging. The PP housing stays inert across common laboratory solvents and buffers in routine use and sustains efficient flow on viscous samples. Where small-volume samples must reach the instrument clean, syringe filtration clears particulates in a single pass.

Technical Specifications

• High tensile strength for stability under elevated differential pressures
• Non-sterile for routine clarification and sample prep
• Alkaline-resistant across a broad range of aqueous buffers
• Absolute pore size rating provides consistent results across filtration protocols
• Low extractable contribution to sensitive analytical preparations

Housing Specifications

• Rigid polypropylene body holds its shape under manual filtration pressure
• Plasticizer-free polyolefin construction keeps the fluid path clean
• Inert polyolefin wall contributes minimal sample adsorption to the filtrate
• Optimized internal geometry minimizes backpressure in service

Filtering particulates upstream protects the column investment your methods depend on. Upstream buffer clarification keeps avoidable particulates out of your flow path before they reach the column inlet or detector.
